gd-YAFSM

Add Artificial Intelligence to your project using this simple State Machine visual editor. It also supports nested state machines to enable modern AI implementations.

Features

• Design StateMachine in a flowchart-like editor
• Visualize the flow of StateMachine & inspect parameters in realtime
• Visualize game/UI state from the flowchart
• Similar workflow as using AnimationTree, and not required to inherit any custom class, just plug and play
• Nested Finite State Machine workflow supported to create complex state machine with ease
• As a Resource, StateMachine can be used repeatedly in different scenarios(StateMachinePlayer) and provide different outcomes based on the input
• Compact data structure for StateMachine resource file

Installation

1. Get gd-YAFSM either from the Github Repo or the Godot Asset Library
2. Copy/paste it in the project’s addons folder
3. Enable it from the plugins tab

Usage

Scene

1. Add a StateMachinePlayer node
2. Select the newly created node and find the new window for editing the state machine
3. Click “Create StateMachine”
4. Right-click on the graph and add a new entry state
5. You can add your own states after the entry
6. Use Shift-Drag to create connections

Code

After setting up the StateMachine node, you can connect with it via code.

There are 2 signals that the StateMachinePlayer triggers:

• transited(from, to)
• updated(state, delta)

You can set the state machine’s properties using set_param or set_trigger commands.
